University of Pennsylvania medical professor Val Arkoosh recently hired Pennsylvania Democratic operative David Madsen as her field director.

Arkoosh is in a crowded Democratic primary to replace Democratic Rep. Allyson Y. Schwartz, who is running for Pennsylvania governor. Former Rep. Marjorie Margolies, D-Pa., state Sen. Daylin Leach and state Rep. Brendan Boyle are also running for the seat.

“Dr. Arkoosh is in the unique position to reach the most voters in this race,” Madsen said in a news release. “I’m looking forward to running a robust field and outreach campaign that shows every voter why Dr. Arkoosh is the right candidate to represent the Pennsylvania 13th.”
